A study was conducted to examine the effects
of rate of extrusion and amount of additive on extruding plastic film. Three
properties of extruded film were measured: tear resistance, gloss and
opacity. The three properties are dependent variables for a multivariate
model with two factors (extrusion rate and additive amount).
The variables in the data set are:
extrusion rate - this has two levels
low (1)
high(2)
additive amount - this has two levels
10% (1)
15% (2)
tear resistance
gloss
opacity
In this on-line
workshop, you will find many movie clips. Each movie clip will demonstrate some specific
usage of SPSS.
Analysis
Using this data set, we will
demonstrate the following data manipulation and analysis:
